Can’t turn off reverse camera screen - Android Head-Units

Hi, just installed my new Android HU in my Golf MK5, I have configured everything and it is working great apart from one issue no matter of searching has got me to the solution.
I do not have a reverse camera installed but every time I put the car in reverse it goes to a black screen as it is was there.
As far as I can tell there are 2 usually solutions to this:
1) Turn the option off under ‘Extra Settings’. My particular unit does not have an Extra Settings menu and I have looked at all other settings and there is no option as far as I can see to disable it.
2) Cut the reverse signal wire going into the head unit. My HU takes the original wiring loom from the car with no extra CANBUS. I have checked wiring diagrams there does not appear to be any dedicated wire for the reverse signal.
Can anyone help me get to the bottom of this please? Let me know if you need any more information.

Option 3: Install Backup Camera
FYI You didn't list the HU model so not sure anyone can help you. On my IDoing uis7862 it's in the settings to disable auto switching.

I'm also looking to disable that option in my head unit. Its a 8227l installed on a Peugeot 407.
For now I will keep the camera for another time when I have the budget for it.

You have to identity the REVERSE wire of the wiring harness. You car provides a +12V signal on it as soon as you enter the reverse gear. You can unpin this wire - don't forget to isolate it.
Another approach could be to disable the Android activity which presents the picture of the reverse camera. This can be done via ADB command (Google for it).
It requires to get the package and activity name but I think there are apps in Google PlayStore available which can list the recently started activities.

Thanks! I will look for that. I'm pondering installing a camera, so this solution would be temporary.

Then, if I were you, I would not invest time in this issue, because it is not a malfunction for you.

[How-To] Fix Aux / Audiopilot for Car-Specific Headunit (Audi A3 8P / Quadlock)

Hello,
I've found a way to fix some problems with my car-specific PX5 Head Unit which is for an Audi A3 8P and would like to share this solution with you.
The first problem I've found was that with the Bose sound-system the volume would slightly change.
This has to do with a feature called Audio Pilot. With the stock radio this could be disabled in the menu.
To disable this behavior you have to put 12V on a Pin of the quadlock connector for the radio. (see first picture)
The second problem was that an original aux-input wasn't working. The needed Pin's were described on the label of the Head Unit, but after some investigation it was clear that they were not connected. So you would have to get them from the quadlock connector to the connector from the head unit.
Not a clean solution if you ask me.
The Solution of both problems was easy, you can make an additional adapter or you can open your head unit to make some cable bridges.
I choose the second method to reduce the adapters in the car behind the head unit. It's a much cleaner look and there are less points of failure.
The attached pictures show which connection I had made to get all functions working without any additional adapters.
As I didn't find any information for this topic, I hope i could help someone with this post.

Install 360 Degree Bird View Cameras to Android HU

has anyone installed 360 degree bird view cameras to any of these android head unit? I am thinking to install one like this .
I have a px5 running Android 8 - I need some confidence from your experience.
Thx in advance.
Do you have one of those big SUV school bus type cars ?
I just dont see whats to be gained, that moving your head couldnt solve.

We all come here to learn. Even if he/she has a Smartcar does it really matter? Tell you the truth I wouldn't mind installing one. I think I remember reading somewhere on here that someone has it installed. You would need to have a video in on the HU. If the HU only has a video in for reverse then obviously it will only work when backing up.
Thank you so much Kouklo for your understanding and insights. Your point about extra video in makes sense. Hope others can share their installation experience with me.

Thank you so much!
So let me give you a bit more info about my project and you may be able to help me more. I have installed an 8" Dasaita Android 8 unit on my 2016 Outlander GT. Now I am planing to install a 360 degree birdview system to this Dasaita system. Could you please help on the following 2 questions? (1) Can I simply plug the male RCA video out from the birdview system to the female RCA of existing rearview camera input of the Dasaita head unit? or an AV IN female RCA female of the Dasaita unit? (2) I found that there is not triggering wire to connect when installing the Dasaita unit, but the birdview system appears need a triggering wire to activate its rearview camera, so not sure hot to handle this issue if I would like to use the existing stock rearview camera with this birdview camera system. I updated to the latest MCU and Android OS, I remember the rearview camera app appears to support 360 degree camera systems now. Thanks so much in advance, I am just preparing myself for the installation. Here is the 360 degree birdview system I bought.
Much appreciated!

what about the manual you recived?
I once looked for this kinda system but later I didnt bought it. My understanding is all cameras are connected to the host and you just nned to connect host to your head unit. I think I saw AV IN rca on my unit, I would try on this port first. Also the host I belive you need to connect it 12V and I dont think you need to connect the "trigger " wire since you have ON/OFF switch on your remote controler.
You can try to connect it to the RCA of the rear camera. Nothing bad will happen.
you can also connect all trigger wires together, than when you hit to reverse it will turn on. I connected triger wire to the reverse rearlight (+).
its not so dificult as it might see

Thank you so much again for your detailed explanation.
1. I am sure it will work on the AV IN because I already have installed a side view and a front-view cameras controlled by a similar "host", I activate the system using a short-cut key on my steering wheel, then using a remote to switch between cameras. The drawbacks are (1) it is not automatic like the rearview camera and (2) you need to press a button or two to activate.
2. for this new project, I would like to (hope I can) integrate the new 360 system's front and 2 side cameras with the stock rearview camera. Offline test seems meet my expectation (I do not need it to be activated when turning left or right - I have yet to find the turning signal wire with constant power - pls do not laugh at me ..... did a lot of searching and asked in various forums).
I will keep you posted on my progress.
Cheers,
John

stock rearview camera is the original on your car?
you can use power cables from main connector of the head unit. there is 12V, ACC and ground. That one that goes in to the back side of the radio and maybe u use some T split conectors.

1. Yes, when I said stock rearview camera, I mean the one came with my car (from the manufacture) when I purchased it new;
2. good idea to use the power supply cables you suggested, do you have pictures handy showing the constant 12V, ACC and ground cables going into the Android head unit?
3. when you say T-split connectors, you mean for the RCA video, right?
Thx again!
John
They are the same color.
T-split connectors for getting power to the host unit of 360 controler.

1. what is that orange BACK wire (the 4th from the top) for? is it for the backup camera?
2. Haha, I misread the 4 speakers as "4 cameras"......
Thx again

it is for connectin trigger wire, for reverse one, so when u put in reverse it will open camera on Head unit.

Any news from your mounting?
I buy the same kit as you.
I ask myself how to keep the image after removing the reverse gear.
Because the image does not remain when you remove the reverse.
I think the central box of this kit keep a signal for a few seconds? or when i put ON with transmitter?
i see this box have a input reverse and output reverse (to connect on the reverse signal on the radio)
But can you confirm that it extends the signal "reverse" by a few seconds to be able to display the view 360 in forward (just after the reverse)
Can you confirm me?
(Sorry i am a belgian man and my English is not verry good )

Thx for writing back and sorry for my delay but mainly because I have never been able to calibrate the birdview - have been communicating with the seller but not very helpful. Maybe you can help me on the calibration.
To answer your question, yes, I followed your earlier instructions for wiring. yes, I can have the birdview on after removing the reverse gear because I used a 2 (in) to 1 (out) RCA video adapter, one input is from the backup camera and the other input is from the birdview unit, so when you put on reverse gear backup camera shows, and when you switch to other gears you will see the birdview unit's image. Hope this answered your question.
Since I am unable to calibrate the birdview, so I am not really using the full feature. Now I am using bot the stock backup camera and the birthview system (I actually use the image from the front camera only) paralell - meaning I leave the stock backup camera as is, and connected the birdview unit to the AV IN and activate it by a quick button (the voice recognition button) on my steering wheel whenever I need to see it.
Hope this is helpful, and after you resolve this issue, hopefully you can help me on calibration.
Cheers,
John
Here's what I did on mine:
1-Connected the reverse signal from the canbox, and the left & right turn signals from the car mirrors to the 360 device.
2-Connected the 360 device trigger signal to the reverse signal input in the head unit.
3-Connected the 360 device RCA output to the head unit reverse camera input.
This way, whenever I turn left, right, or put the car on reverse, the 360 view together with left, right, or rear camera views, gets automatically displayed on the head unit. When I put the car out of reverse, the 360 device replaces the rear camera view with the front camera view and stays on for a few seconds before turning off.
I can also press the flasher to get the 360 camera on anytime.
It's very simple
I'have mounted wenichen 360 degree bird view on my rover 75
Connect reverse light + on the cable rear cam.
Connect right and left turn light on cable of camera
Connect video out on the rear cam input of PX5 and the white cable on the px5 reverse cable.
When you turn on left or right or put reverse, the px5 switch the screen to show 360 bird view
I abandoned the idea of putting the box "bird 360"
the new PX6 has the plugs to connect a camera to the front!
(The px5 has the same plug but is not wired)
I managed to get the new RCA plugs and now I have an input and a power supply to connect a camera to the front!
remains more than to change the option in the canbus to activate the camera at the front just after the reverse

Android TPMS How does it work

Hello. guys
i got hold of a TPMS kit from Teyes. 4 tpms in tyre sensors, and usb reciver device with usb. i also got the Teyes cc2plus head unit.
My problem is that i have to sets of tyres. Winter/summer. So teyes or other brands that supports android 10. only ship with one set of 4 sensors.
I Have a Autel MaxiTPMS TS508 unit. I tried to read the sensor but faild to read. As i know the sensor is on 433mhz. and like other china products no markings or numbers.
I would think it was a easy job to just read the sensor and wright to a new one. so then you would have 2 duplicate sets. but no.
I am hoping some of you have the knowledge to help me.

What about the teyes thread that discusses your unit. You have to put some effort in on xda, there are no guys
First contact for support is Teyes, what did they suggest you do before returning defective product
I'd like to read my factory(!) TPMS sensors with my android head unit. Since OBD2 dongles don't seem to provide TPMS data (shame...), I think buying an aftermarket TPMS set, solely for the USB receiver unit. Since I can read TPMS data using my RTL-SDR dongle from my PC with no problem, it may be working, just a question of configuration.
And yes, "question of configuration". Did anyone around here have experiments / experience with such an USB receiver unit? Or am I just overcomplicating things?
@hurjup
Check the CAN settings in your unit. The OEM TPMS data are provided via CAN.
Depends on the car if the CAN box is able to translate these data to be able to see that in your radio.

Could you explain a bit "can box"?
For the very same(?) head units sometimes an additional box (can box?) was provided and sometimes not. Amyway, I didn't receive anything like that for my suzuki s-cross, which looks normal to me. Is it embedded into the unit (which doesn't implement TPMS reading)? Or is it not needed for general functionality?
In short, knowing my car type, can I improve the situation with TPMS, or it is better just let it go?
Thank you in advance...
Well...
I don´t know if your unit has an internal CAN-Box or not. Please ask your reseller.
Nevertheless:
Even your suzuki s-cross should provide these data via CAN.
So possible issues could be:
No CAN-box internal or external (but I expect to get clamp 15, Reverse gear and some other stuff to be provided by any can box)
CAN settings in the unit are wrong
Wrong car set
wrong CAN box set
But most of the time you run into the issue that the CAN box (internal or external) does not translate these data. (most of the cars are not supported for data more than SW-Buttons, Clamp 15, Reverse gear, e-brake)
You should contact your reseller and ask if there is a CAN Adapter available which decodes these data for your car.
I searched already, but did not find any for your car which should be able to do what you want.
I vote for the "CAN box does not translate these data" option. I've contacted my seller, but expect multiple rounds when it tries to google translate "can type" or "can adapter" before hitting a dead end. I don't expect any resolution of this problem through support, simply because the product page wanted to sell me an aftermarket TPMS set for my particular car type.
Some time possibly I'll make a try with such a set, maybe an app dev was lazy enough to adapt rtl_433 with minimal modifications and it will just work.
You´re not allone...
For my Mitsubishi I even don´t get the door open messages and climate control through the CAN box.
Even intire OEM TPMS is not visible. Just visible in the cluster. It is available on CAN, but not translated.
If you would own a VW Golf as example, you would get all this stuff on your unit....so guess why no one get´s on the CAN traces and translates the signals for cars which are not sold that often...

Joying Headunit Video In Problem

Hi All,
Have actually really enjoyed the headunit so far, but am using a wireless reverse camera setup. It was recommended to use the video in and just select this when I want to view the camera (because there is no wiring to tell the headunit when the car is in reverse), but not having much luck.
The wireless transmitter/receivers power on and then connect with a blue light, but I'm not sure what to do next, as there doesn't seem to be anywhere to view video in. I found and activated the "Front camera" app assuming that this might show the feed, but when I open it I just get the message that "Driving status. video closed while driving". I'm not sure if this is even the right app to view the feed though, so any help would be much appreciated!
why dont you just use the reverse lights to trigger backup cam
Thanks very much for your reply. The wireless setup I have doesn't have a "back" cable? Which I believe is the trigger to tell the headunit to show the feed for the reverse camera? My setup is currently powered by the reverse lights, but there is nothing to tell the headunit that the car is in reverse (which is why I was recommended to just use the video in and manually turn it on when I'm in reverse)? Having said that, it's my first time doing anything like this, so I really don't know what I'm talking about...

Navtree Head Unit Battery Issue

Hi, New to the site and a greyhead who knows nothing about the electronics of these things. I installed a Navitree Y1E Android 11 4core 2+32GB Car DVD player for Ford Focus 2 2004-2011 audio for car video AM FM RDS 4G WIFI BT in my 201 Ford Focus. All appeared well as fitting was easy. All looked great and now I have found there is a constant live feed to the unit that is the possibe cause of a flat battery. My son is a mechanic and accepts he is not electronically knowledgeable, but he tested the wires and found a Yellow wire that was live and for memory, but there was a red wire that was permantly live and should be a switch feed. Can anyone advise if they have had experience with this model (Direct from China) and what is happening? Appreciate any help.

Hi Guys asnyone able to help. No help from supplier and looks like I will have to ditch the headunit..
Why would you ditch the head unit? It needs the permanent power on the yellow wire and a switched feed on the red wire. Your vehicle is currently not providing this so either you have wired the unit to the wrong feed or there currently isn't one so you'd need to find a connection in the vehicle which does switch with the key and run it to the red wire. As the red wire is only a sensing input it doesn't need heavy wiring.
It is not a head unit fault.
Note some vehicles supply the switching information to the stock head unit via the CANbus, yours may be like that and would explain the lack of a switched feed at present but you can easily overcome this.

Mr.TT_NZ​Thanks for replying..appreciate comments..The red wire is going into the canbus via a 20 pin connector if it is cut the problem seems solved, so are you saying that I should have a switch cable run to that? See image for wiring.
Ah so you do have a CANbus module, I believe there are some issues with switching via those modules but I've never had one to play with.
You could try removing the red wire from the CANbus module and connecting a switched feed to it instead (not as well as) so the head unit only gets its switch control from your new wire. Maybe that CANbus module is not exactly correct for your model of car, there are so many variations even within a certain model that it is hard to see how the people who write the software for the modules can keep up with all of them.

Thanks again. I will try this...did a bit off research on the canbus and there is no UK retailer who will sell me a Ford canbus and guarantee it will work! Most said it would be a sale with no return.. Hey Ho..
